Though it may not look like it even HMTK dot com runs on WordPress.
WordPress dot org just released a new version of WordPress with many excellent new features. Several of these features are truly great and you can see them highlighted below.
1.Native tagging support allows you to use tags in addition to categories on your posts, if you so choose. We've included importers for the Ultimate Tag Warrior, Jerome's Keywords, Simple Tags, and Bunny's Technorati Tag plugins so if you've already been using a tagging plugin you can bring your data into the new system. The tagging system is also wicked-fast, so your host won't mind.
2. Our new update notification lets you know when there is a new release of WordPress or when any of the plugins you use has an update available. It works by sending your blog URL, plugins, and version information to our new api.wordpress.org service which then compares it to the plugin database and tells you whats the latest and greatest you can use.
3. We've cleaned up URLs a bunch in a feature we call canonical URLs which does things like enforce your no-www preference, redirect posts with changed slugs so a link never goes bad, redirect URLs that get cut off in emails on similar to the correct post, and much more. This helps your users, and it also helps your search engine optimization, as search engines like for each page to be available in one canonical location. More info here.
4. Our new pending review feature will be great for multi-author blogs. It allows authors to submit a post for review by an editor or administrator, where before they would just have to save a draft and hope someone noticed it.
5. There is new advanced WYSIWYG functionality (we call it the kitchen sink button) that allows you to access some features of TinyMCE that were previously hidden.
These are all great features but I have encountered a problem.
I use the Google Sitemap generator plugin to keep my sitemap up to date. This plugin no longer works and instead throws a database error.
This is the error I get here:
WordPress database error: [Table 'tv_news.wp_post2cat' doesn't exist]
SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM `wp_posts` p LEFT JOIN `wp_post2cat` pc ON p.ID = pc.post_id LEFT JOIN `wp_categories` c ON pc.category_id = c.cat_ID WHERE post_status = 'publish' GROUP BY cat_ID
I get a similar error message on all of my blogs that run WordPress and the Google Sitemap plugin.
If you use the google Sitemap plugin I suggest you wait before upgrading your WordPress installation.
Update
The fine folks who created the original Google Sitemaps plugin for WordPress have released a new version that works with wordPress version 2.3. The plugin has been renamed to Google (XML) Sitemaps Generator for wordPress. After installing this new version of the plugin the sitemap was created without errors.
